Abstract The Interstellar Map** and Acceleration Probe (IMAP) is a revolutionary mission
that simultaneously investigates two of the most important overarching issues in …

The GAS-instrument onboard the space probe Ulysses is designed to measure the local
angular distribution of the flow of interstellar neutral He-atoms within≈ 3 AU distance from …

We present an empirical dynamical model of the LISM based on 270 radial velocity
measurements for 157 sight lines toward nearby stars. Physical parameter measurements …

Using an absorption cell, we measured the Doppler shifts of the interstellar hydrogen
resonance glow to show the direction of the neutral hydrogen flow as it enters the inner …

Neutral atom imaging of the interstellar gas flow in the inner heliosphere provides the most
detailed information on physical conditions of the surrounding interstellar medium (ISM) and …

Both heliophysics and planetary physics seek to understand the complex nature of the solar
wind's interaction with solar system obstacles like Earth's magnetosphere, the ionospheres …

Because of its high ionization potential and weak interaction with hydrogen, neutral
interstellar helium (NISHe) is almost unaffected at the heliospheric interface with the …

Past analysis has shown that the heliosphere structure can be deduced from correlations
between long-scale solar wind pressure evolution and energetic neutral atom emissions …

Context. Ongoing measurements of the cosmic radiation (nuclear, electronic, and γ-ray) are
providing additional insight into cosmic-ray physics. A comprehensive picture of these data …

Interstellar pickup ions are an ubiquitous and thermodynamically important component of
the solar wind plasma in the heliosphere. These PUIs are born from the ionization of the …
